TCS34725 - RGB Color Sensor with IR Filter and White LED - (AD20815)

Description:

Your electronic devices can now see in dazzling color, thanks to this lovely color light sensor. We've found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and located on the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you'll get much truer color than most sensors, since humans don't see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass.

We've added supporting circuitry as well, such as a 3.3V regulator so you can safely power the breakout with 3-5V DC and level shifting for the I₂C pins so it can be used with 3.3V or 5V logic. Finally, we've specified a neutral 4150°K temperature LED with a MOSFET driver built in to illuminate what you're trying to sense. The LED can be easily turned on or off by any logic level output.

Connect to any microcontroller with I₂C and our example code will get you started fast with 4-channel readings. We include example code for detecting light lux and temperature, pulled from the evaluation board software.

A detailed tutorial is here - check out our Arduino library and follow our tutorial to install it. Wire up the sensor by connecting VDD to 3-5VDC, Ground to common ground, SCL to I₂C Clock, and SDA to I₂C Data on your Arduino. Restart the IDE, select the example program and start putting your favorite fruits next to the sensor.
